Search test data directory path dynamically

[weiihann]

Description

This PR modifies the implementation of finding the target test data directory. The issue with the existing implementation is that if a user changes the repository's name from juno to whatever, the tests will fail. Also, any tests that rely on NewTestClient in cmd/juno will fail because the base directory extracted will be ../juno/cmd/juno instead of ../juno.

I think the function can be simplified as follows:

Suggested change

	func findTargetDirectory(targetRelPath string) (string, error) {
	wd, err := os.Getwd()
	if err != nil {
	return "", err
	}
	for root := wd; ; root = filepath.Dir(root) {
	if _, err := os.Stat(filepath.Join(root, targetRelPath)); err == nil {
	return filepath.Join(root, targetRelPath), nil
	} else if !os.IsNotExist(err) {
	return "", err
	} else if newRoot := filepath.Dir(root); newRoot == root {
	return "", os.ErrNotExist
	}
	}
	}
	func findTargetDirectory(targetRelPath string) (string, error) {
	root, err := os.Getwd()
	if err != nil {
	return "", err
	}
	for {
	targetPath := filepath.Join(root, targetRelPath)
	if _, err := os.Stat(targetPath); err == nil {
	return targetPath, nil
	} else if !os.IsNotExist(err) {
	return "", err
	}
	newRoot := filepath.Dir(root)
	if newRoot == root {
	return "", os.ErrNotExist
	}
	root = newRoot
	}
	}
